The slide groove 328 can limit the movement trajectory of the threaded sleeves 405. The output shaft of the servo motor 401 rotates forward to gradually bring the two movable plates 321 closer together, and the output shaft of the servo motor 401 rotates reversely to drive the two movable plates 321 to gradually move away from each other.

Since the threads on the surfaces of the two threaded rods 404 are arranged in opposite directions, the two threaded sleeves 405 can be driven to move toward the middle, and then the threaded sleeves 405 can drive the movable plate 321 to move, and the spacing between the movable plates 321 can be adjusted. The deviation correction sensor 202 can monitor the movement position of the paper and send the monitoring data to the PLC controller 201. The PLC controller The controller 201 determines whether the paper is offset according to the monitoring data. When the output end of the electric push rod 205 contracts or extends, it pushes the slider 207 on one side to slide along the surface of the slider 206 on one side. When the slider 207 on one side moves, it drives the correction roller 204 to move through the mounting block 208 on one side. When the correction roller 204 moves, it drives the mounting block 208 on the other side to slide along the surface of the slider 207 on the other side along the surface of the slider 206 on the other side. During the movement of the correction roller 204, the position of the paper can be adjusted, so that the movement position of the paper can be corrected. The adjusting bolt 327 is rotated clockwise, and the adjusting bolt 327 is rotated downward along the inner cavity of the threaded hole 326, thereby driving the pressure plate 322 to move downward. When the pressure plate 322 moves downward, it drives the upper pressure wheel 324 to move downward, so that the surface of the upper pressure wheel 324 contacts the paper, thereby limiting the movement trajectory of the paper.
